*1: Protective structure is based upon EN60529.*2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). To

use other motors, care must be taken to prevent the rated motor current (50Hz) from exceeding the rated output current of the inverter.

*3: The output voltage decreases as the main power supply voltage decreases.(Except for use of the AVR function)

*4: To operate the motor beyond 50/60 Hz, consult the motor manufacturerabout the maximum allowable rotation speed.

*5: The braking torque at capacitive feedback is the average decelerationtorque at the shortest deceleration (stoppage from 50/60 Hz) of the motoritself. It is not the continuous regenerative braking torque. And the averagedeceleration torque varies with motor loss. This value decreases whenoperating beyond 50/60 Hz. If a large regeneration torque is required, the

optional Dynamic braking unit should be used.*6: The frequency command is the maximum frequency at 9.8 V for input voltage

0 ~ 10 VDC, or at 19.6 mA for input current 4 ~ 20 mA. If this characteristicis not convenient, contact your Hitachi sales representative.

*7: To use the inverter at 40°C or higher, reduce carrier frequency 2kHz andderate output current 80%, and remove the top cover.

*8: The storage temperature refers to the short-term temperature duringtransport.

*9: Conforms to the test method specified in JIS C0911 (1984). For the modeltypes excluded in the standard specifications, contact your Hitachi salesrepresentative.

Digital operatorDescription

When the motor is restrained or suddenly reduced inspeed, a large current is charged to the inverter,causing a fault. When the inverter detects 205% peakcurrent for the rated current of the inverter,Over currentis occurred.

When the inverter output current causes the motor to overload, the electronicthermal trip in the inverter cuts off the inverter output.

If regenerative energy from the motor or the main power supply voltage is high,the protective circuit activates to cut off the inverter output when the voltage ofthe converter section exceeds the specification.

The inverter output is cut off when EEPROM in the inverter has an error due toexternal noise, excessive temperature rise, or other factor.

When the input voltage received by the inverter decreases, the control circuitdoes not function normally. When the input voltage is below thespecification, the inverter output is cut off.

The inverter output is cut off when the inverter CPU has a malfunction or anerror.

When the external equipment or unit has an error, the inverter receives thecorresponding signal and cuts off the output.

The USP error is indicated when the power is turned on with the inverter inRUN state. (Enabled when the USP function is selected.)

Ground fault is detected between the inverter output section and the motorwhen the power is turned on, to protect the inverter.

When the input voltage is higher than the specified value, it is detected 100seconds after power is turned on and the output is cut off.

When the temperature in the main circuit increases due to cooling fan stop,the inverter output is cut off. (Only for the model type with cooling fan)

When the resistance value of the external thermistor is too large, the equipmentdetects the abnormal condition of the thermistor and then cut off the output(when PTC function is selected)

Function

This is useful when harmonic suppression measures must be taken,when the main power voltage unbalance rate exceeds 3% and themain power capacity exceeds 500kVA, or when a sudden powervoltage variation occurs.It also helps to improve the power factor.

Noise may occur in a nearby radio, etc., via the mainpower supplyside wiring when using the inverter. This filter helps to reduce thenoise; radiated noise reduction.

Reduces the conductive noise on the main power wires generatedfrom the main power supply. Connect to the inverter primary side(input side).

Reduces noise radiated from the main power wiring on the input side.

Suppresses harmonics generated by the inverter.

This is useful for increasing the control torque of the inverter, forfrequently repeating ON-OFF of the inverter, or for decelerating theload with a large inertial moment (GD2).

This is installed between the inverter and the motor to reduce noiseradiated from the control power wiring. It is useful for reducingradio-wave disturbance in a radio or TV set and for preventingmalfunction of measuring instruments or sensors

Useful for reducing noise produced in the inverter output side. (It is usable on either the input or output side.)

Vibration may increase when driving a general-purpose motor with aninverter as compared with operation on commercial power.Connecting this reactor between the inverter and the motor allowsreduction of motor pulsation. When the wiring between the inverter andthe motor is 10 m or more, inserting the reactor prevents thermal relaymalfunction caused by harmonics resulting from inverter switching.A current sensor can be used instead of the thermal relay.

A system applying a voltage-type PWM inverter with IGBT may have surge voltage at the motor terminals resulting from the cable constants includingthe cable length and the cable laying method. Depending on the surge current magnification, the motor coil insulation may be degraded. Inparticular, when a 400V-class motor is used, a longer cable is used, and critical loss can occur, take the following countermeasures: (1) install the LCR filter between the inverter and the motor, (2) install the AC reactor between the inverter and the motor, or (3) enhance the insulation of the motor coil.

[Application to the 400V-class motor]

Notes on Use[Drive]

The overspeed endurance of a general-purpose motor is 120% of the rated speed for 2 minutes (JIS C4004). Foroperation at higher than 60 Hz, it is required to examine the allowable torque of the motor, useful life of bearings,noise, vibration, etc. In this case, be sure to consult the motor manufacturer as the maximum allowable rpm differsdepending on the motor capacity, etc.

The torque characteristics of driving a general-purpose motor with an inverter differ from those of driving it withcommercial power (starting torque decreases in particular). Carefully check the load torque characteristic of aconnected machine and the driving torque characteristic of the motor.

An inverter-driven general-purpose motor heats up swiftly at lower speeds. Consequently, the torque level permittingcontinuous use decreases with lower motor speeds. Carefully check the torque characteristics.

When run by an inverter, a general-purpose motor generates noise slightly greater than with commercial power.

When run by an inverter at variable speeds, the motor may generate vibration, especially because of (a) unbalance ofthe rotor including a connected machine, or (b) resonance caused by the natural vibration frequency of a mechanicalsystem. Particularly, be careful of (b) when operating at variable speeds a machine previously fitted with a constantspeed motor. Vibration can be minimized by (1) avoiding resonance points using the frequency jump function of theinverter, (2) using a tire-shaped coupling, or (3) placing a rubber shock absorber beneath the motor base.

Under continued, low-speed operation, oil lubrication can deteriorate in a power transmission mechanism with an oil-type gear box (gear motor) or reducer. Check with the motor manufacturer for the permissible range of continuousspeed. To operate at more than 60 Hz, confirm the machine’s ability to withstand the centrifugal force generated.

The allowable rotation range of continuous drive varies depending on the lubrication method or motor manufacturer.(Particularly in case of oil lubrication, pay attention to the low frequency range.) The Hitachi GA/GX/CX gear motors areof a grease lubrication type. Their grease lubrication capability remains unchanged even if the motor rotating speeddecreases.

For use of a brake-equipped motor, be sure to connect the braking power supply from the primary side of the inverter.

There are different kinds of pole-change motors, constant output characteristic type, constant torque characteristictype, etc., and with different rated current values. In motor selection, check the maximum allowable current for eachmotor of a different pole count. At the time of pole changing, be sure to stop the motor.

The rated current of a submersible motor is significantly larger than that of the general-purpose motor. In inverterselection, be sure to check the rated current of the motor.

Inverter drive is not suitable for a safety-enhanced explosion-proof type of motor. The inverter should be used incombination with a pressure-proof explosion-proof type of motor.* Explosion-proof verification is not available for L100 Series. For explosion-proof operation, use other series of motors.

In most cases, the synchronous (MS) motor and the high-speed (HFM) motor are designed and manufactured to meetthe specifications suitable for a connected machine. As to inverter selection, consult the manufacturer.

A single-phase motor is not suitable for variable-speed operation by inverter drive. Therefore, use a three-phase motor.

Run or stop of the inverter must be done with the keys on the operator panel or through a control circuit terminal.Do not operate by installing a electromagnetic contactor (Mg) in the main circuit.

When the protective function is operating or the power supply stops, the motor enters the free run stop state. Whenan emergency stop is required or when the motor should be kept stopped, use the mechanical brake.

A max. 360 Hz can be selected on the L100 Series. However, a two-pole motor can attain up to approx. 21,600rpm, which is extremely dangerous. Therefore, carefully make selection and settings by checking the mechanicalstrength of the motor and connected machines. Consult the motor manufacturer when it is necessary to drive astandard (general-purpose) motor at over 60 Hz. A full line of high-speed motors is available from Hitachi.

[Installation location and operating environment]

Avoid installation in areas of high temperature, excessive humidity, or where moisture can easily collect, as well as areas that are dusty, subject to corrosivegasses, mist of liquid for grinding, or salt. Install the inverter away from direct sunlight in a well-ventilated room that is free of vibration. The inverter can beoperated in the ambient temperature range from -10 to 50: .(carrier frequency and output current must be reduced in the range of 40 to 50: )

Before use, be sure to read through the Instruction Manual to insure proper use of the inverter. Note that the inverter requires electrical wiring; a specialist should carry out the wiring. The inverter in this catalog is designed for general industrial applications. For special applications in fields such as aircraft, outer space, nuclear

power, electrical power, transport vehicles, clinics, and submarine relay equipment, please consult with us in advance. For application in a facility where human life is involved or serious losses may occur, make sure to provide safety devices to avoid a serious

accident. The inverter is intended for use with a three-phase AC motor. For use with a load other than this, please consult with us.

Notes on Peripheral Equipment Selection

An inverter run by a private power generator may overheat the generator or suffer from a deformed output voltagewaveform of the generator. Generally, the generator capacity should be five times that of the inverter (kVA) in aPWM control system, or six times greater in a PAM control system.

(1) Be sure to connect main power wires with R, S, and T (input) terminals and motor wires to U, V, and W terminals(output). (Incorrect connection will cause a breakdown.)

(2) Be sure to provide a grounding connection with the ground terminal ( ).

When an electromagnetic contactor is installed between the inverter and the motor, do not perform on-off switchingduring running operation.

When used with standard applicable output motors (Hitachi standard three-phase squirrel-cage four-pole motors), theL100 Series do not need a thermal relay for motor protection due to the internal electronic protective circuit. A thermalrelay, however, should be used:• during continuous running at a range beyond 30 to 60 Hz. • for motors exceeding the range of electronic thermal adjustment (rated current). • when several motors are driven by the same inverter; install a thermal relay for each motor. • The RC value of the thermal relay should be more than 1.1 times the rated current of the motor. Where the wiringlength is 10 m or more, the thermal relay tends to turn off readily. In this case, provide an AC reactor on the outputside or use a current sensor. See the item for the thermal relay malfunction preventive AC reactor on page 16.

Install a circuit breaker on the main power input side to protect inverter wiring and ensure personal safety. Choose aninverter-compatible circuit breaker. The conventional type may malfunction due to harmonics from the inverter. Formore information, consult the circuit breaker manufacturer.

The wiring distance between the inverter and the remote operator panel should be 20 meters or less. When thisdistance is exceeded, use CVD-E (current-voltage converter) or RCD-E (remote control device). Shielded cableshould be used on the wiring. Beware of voltage drops on main circuit wires. (A large voltage drop reduces torque.)

If the earth leakage relay (or earth leakage breaker) is used, it should have a sensitivity level of 15 mA or more (perinverter). The leakage current differs depending on the cable length; see page xx.

Do not use a capacitor for power factor improvement between the inverter and the motor because the high-frequencycomponents of the inverter output may overheat or damage the capacitor

(1) High-frequency components are included in the input/output of the inverter main circuit, and they may cause interference in a transmitter, radio,or sensor if used near the inverter. The interference can be minimized by attaching noise filters (option) in the inverter circuitry.

(2) The switching action of an inverter causes an increase in leakage current. Be sure to ground the inverter and the motor.

Because a smoothing capacitor deteriorates as it undergoes internal chemical reaction, it should normally bereplaced every five years. Be aware, however, that its life expectancy is considerably shorter when the inverter issubjected to such adverse factors as high temperatures or heavy loads exceeding the rated current of the inverter. The approximate lifetime of the capacitor is as shown in the figure at the right when it is used 12 hours daily(according to the “Instructions for Periodic Inspection of General-Purpose Inverter” (JEMA).)Also, such consumable parts as a cooling fan should be replaced. (Maintenance inspection and parts replacementmust be performed by only specified trained personnel.)

In the cases below involving a general-purpose inverter, a large peak current flows on the main power supply side,and is able to destroy the converter module. Where such situations are foreseen or the connected equipment mustbe highly reliable, install an AC reactor between the power supply and the inverter. Also, where influence ofindirect lightning strike is possible, install a lightning conductor.(A) The unbalance factor of the power supply is 3% or higher. (Note)(B) The power supply capacity is at least 10 times greater than the inverter capacity (the power supply capacity is

500 kVA or more).(C) Abrupt power supply changes are expected. Examples:

(1) Several inverters are interconnected with a short bus. (2) A thyristor converter and an inverter are interconnected with a short bus. (3) An installed phase advance capacitor opens and closes.

In cases (A), (B) and (C), it is recommended to install an AC reactor on the main power supply side.Note: Example calculation with VRS = 200V, VST = 203V, VTR = 197V

VRS : R-S line voltage, VST : S-T line voltage, VTR : T-R line voltage
